I don't think there's any need for eval - I'll leave the sermon about why
eval is a Bad Thing for someone else - and if your objects are going to
spend most of their "lives" in a list or dictionary, they don't really need
meaningful individual names. (I mean, instead of naming each one class1,
class2, etc. you can simply refer to them as classDict[1], classDict[2],
etc. or classList[1], etc.)
How's this:
#====================================
class thingy():
example = "Just testing - "
def __init__(self, num):
self.example = self.example + str(num)
thang = {}
for x in range(1,4):
thang[x] = thingy(x)
for item, value in thang.iteritems():
print item, value.example
#=====================================
